"I called this one. This is another stall tactic. This is the beginning of an ongoing medical thing to keep himself from trial," said Steven Davis, whose 26-year-old sister, Debbie, is one of Bulger's alleged victims.

A source close to the Bulger family said that it "may be something less than that" when asked if Bulger had suffered a heart attack.

NewsCenter 5 previously reported that Bulger struggles with incontinence and visits the prison infirmary on a daily basis.

In December, Bulger was treated for heart problems at Boston Medical Center.

Bulger, the former leader of the Winter Hill Gang, is accused of murdering 19 people.

Davis fears Bulger may not make it to his scheduled trial date in March.

"I live eat and breathe this thing. I want it to end somewhere," Steven Davis said. "I'd like it to end with a jury and judge to come back and give him a guilty."
